It's a fact.
That's because we're not eating our great-grandmother's vegetables!
Yes, there are plenty of those who will say if you eat right, you don't need supplements. And there is that concern that with the plethora that's out there, you may pick some that could interact badly with prescription medications you may be taking.
But to keep it simple here, my readings convince me that if you're eating plenty of fruits and vegetables, a good quality multi-vitamin and extra vitamin D3 is a great combination. There's lots of research out there supporting taking vitamin D3 because most of us don't get enough sunlight exposure to provide what our bodies need.
And the case for a multi vitamin is a no brainer because the mineral quality of our soils has been seriously depleted as a result of large scale growing practices. That's the reason why buying organic is mainly to avoid harmful pesticide levels, as opposed to a product that's as nutrient rich as what was grown decades ago.
Look for a whole foods vitamin, rather than those that are synthetically produced, because your body will metabolize them more efficiently.
If you are dealing with a serious health issue, however, consult a nutritionist for advice on higher levels of supplementing.
